Hi,

in my application, I have 3 possible contexts: Exports, Reports and Sessions. In my application I have only one RadGridView and the RadGridView layout change regarding the current active context. Regarding the context, the grid have differents converters for columns who contains enumeration values.

Before changing the grid layout, I call the following methods:

    - GV.GroupDescriptors.Clear()
    - GV.SortDescriptors.Clear()
    - GV.FilterDescriptors.Clear()

I don`t know why but when I switch from one context to another, after I change the layout of my grid, if I go on a column which contain a converter for my enumeration, I click on the filter dialog button, when the filter dialog appear, in the top part of the filter dialog, I have all existing values in my columns that I can check or uncheck but when I click in the combobox to apply a specific filter, the values in the dropdown it's the value corresponding to my previous context.

Thank's

I have a reference in my xaml as such:
xmlns:maskedInput="clr-namespace:Telerik.Windows.Controls.MaskedInput;assembly=Telerik.Windows.Controls.Input"

I am trying to set the Minimum value in the style as such:
        <Style x:Key="RadMaskedCurrencyInputStyle" TargetType="telerik:RadMaskedCurrencyInput">
            <Setter Property="maskedInput:MaskedInputExtensions.Minimum" Value="0" />
        </Style>

This throws an exception at run time:  
System.Windows.Markup.XamlParseException occurred
  Message='Set property 'System.Windows.Setter.Property' threw an exception.' Line number '10' and line position '14'.

Is this a flaw with Telerik's implementation of the Minimum dependency property?  I am using version 2011 SP1.

Thanks,

Hello,

I have my application in "pt-PT" culture, and have this column.


introducing "20.2", it places "202,00".
introducing "20,2" it places "20,20".

In "en-US" culture works well.

So, how can i give the same behavior for dot and comma?

Thanks

Hi,
I need a sample code for to create the parent and child grid.

Here is a code sample that gets the Type Of the Next & Previous Annotation at the caret position.
.
Get TypeOf Next Annotation:


Get TypeOf Previous Annotation:


This is how you can use the methods:

I hope this help you as it did me.

p.s. This code was mostly given to me by the Telerik support team via a ticket that I sent.

I have a column in my RadGridView that displays some text and then also contains a button that should only be visible to users with permission to change the data.  I'm using MVVM and the viewmodel exposes a boolean property named UserHasWriteAccess that indicates the user's permission level.  The column and its datatemplate are defined as follows.


When UserHasWriteAccess is false, the button's visibility binding works fine most of the time (~99%) and the button does not show.  However, as the user scrolls up and down through the grid, eventually intermittent binding errors will suddenly appear for a row or two for which the binding worked previously.  Sometimes the user has to scroll up and down several times before it happens.  Other times it's immediate.  The errors say:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.RadGridView', AncestorLevel='1''. BindingExpression:Path=DataContext.UserHasWriteAccess; DataItem=null; target element is 'Button' (Name=''); target property is 'Visibility' (type 'Visibility')

Curiously, when I inspect an errored binding using Snoop, it suddenly works again.

Is there a known issue with ancestor binding in RadGridView?

Hello!

We are using MVVM pattern to build our application. One of our views uses number of NumericUpDown controls. If text of some NumericUpDown is set to empty string by user control displays red frame (see screenshot "validation error"). Property definition you can find in screenshot named "amount property".

The problem is that view model is not updated when text is empty and red frame is displayed. E.g. model still contains previous value.

What is correct way to notify View Model about missing data? Keep in mind that we have significant number of views and each contains set of numeric controls.

We have a WPF app which uses RadGrid. As part of the app functionality, we want the grid selection unit to always be of type "row". In addition to this, we also want to expose a mechanism where the user can select a cell value for copy/paste to clipboard. Is there a way to do this? For example, double clicking a cell copies the cell value where as single click always selects the row. Or right click on cell exposes the option to "Copy cell" value? 

Thanks!

Does the wpf GridView support direct binding to SqlCeResultSet?

Hi,

I'm using RadControls for WPF (version 2012.1.326.40), and my question is about the RadTreeView.
Is it possible to show an overlay image over the RadTreeViewItem's DefaultImageSrc ?

Best regards,
